The city of Vienna is modeled with accuracy less than 10cm (4 in). The model shows many historic buildings in the core. It was developed using BS Contact Studio and is stored and delivered using the V3D Compressed Binary encoding (X3DB). The scene requires a recent version of BS Contact to be correctly installed. If not, a wizard will assist you with the download and installation. While this scene is cross-platform, the BS Contact installation wizard is only designed for PCs and will not work for Macintosh computers.
